Normal step motors are using Insulation Class B, and guarantee the 20,000 hour at 130℃.  (100 ℃ - 100,000 Hour Life Guarantee)

​

FASTECH products use stepping motors and have high torque characteristics at low speeds. Therefore, heat is generated due to high energy consumption due to the characteristics of maintaining high torques in general equipment applications.
So temperature issue is physical characteristic of step motor compare to general servo system.
 
However, since FASTECH’s products have current control characteristics according to the load, compared to other products that consume constant current regardless of the motor’s operating conditions, FASTECH consumes current according to the load characteristics to minimize heat generation and save energy. In addition, since the software that controls heat generation is applied separately, it has much better heat generation characteristics compared to other step motors.

​

Also FASTECH adopts Boost Current function onto our products to prevent losing of torque under high speed range and it is very much differentiated from other conventional stepping motor system. In this case, little bit less performance of temperature can be expected, so please consult with FASTECH sales team of our distributor before selection of product.

This figure compares the current status according to the load status of the motor.
* Test product : Ezi-SERVO Plus-R, Motor size 60L

[Current control characteristic by load]

​

Current value is 1.6A under Min. Load (No Load), and 4.0A under Max. Load. (Based on 60mm motor) So it automatically controls according to load variation. Therefore, it can suppress motor heating.
